syntax error on dart sdk version with Flutter 3.0.3

[melissa-q-amica]

Describe the bug

When upgrading to flutter 3.0.3 I received the following error: Expected version number after ">=" in ">=2.12-0-0 <3.0.0", got "2.12-0-0 <3.0.0".

Manually changing the version to 2.12.0 resolved this issue. I believe the hyphens or dashes are causing a syntax error.

To Reproduce Steps to reproduce the behavior:

1. Go to '...'
2. Click on '....'
3. Scroll down to '....'
4. See error

Expected behavior A clear and concise description of what you expected to happen.

Screenshots If applicable, add screenshots to help explain your problem.

Hi @melissa-q-amica 👋 Thanks for opening an issue!

Can you clear your pub cache and try again?

dart pub cache clean

Issue still occurs after dart pub cache clean

I'm also experiencing this bug with Mocktail and Mockingjay.

Changing sdk to 2.12.0 does not solve it.

Error message: Invalid version constraint: Expected version number after ">=" in ">=2.12-0-0 <3.0.0", got "2.12-0-0 <3.0.0".

I would recommend removing mocktail from pub-cache and reinstalling. Also please ensure you're using the latest version of mocktail by checking the version in your pubspec.lock.

If you're still having trouble can you please share a link to a minimal reproduction sample? Thanks!

I'm currently not testing android.

I've run: dart pub cache clean

pubspec.yaml:

mocktail: ^0.3.0

when running flutter pub get:

Error on line 8, column 8 of /Users/regisksc/Dev/flutter/.pub-cache/hosted/pub.dartlang.org/mocktail-0.1.2/pubspec.yaml: Invalid version constraint: Expected version number after ">=" in ">=2.12-0-0 <3.0.0", got "2.12-0-0 <3.0.0". ╷ 8 │ sdk: ">=2.12-0-0 <3.0.0" │ ^^^^^^^^^^^^^^^^^^^ ╵ pub get failed (65; ╵) exit code 65

#### EDIT:

manually changing mocktail's pubspec sdk version to 2.12.0 <3.0.0 makes it work.
did so by editing with:
nano /$PATH_TO_FLUTTER/.pub-cache/hosted/pub.dartlang.org/mocktail-0.1.2/pubspec.yaml
